Did this ever work for you? I get a DDE error :
SBIE2205 Service not implemented: DDE 000003E6
Same as reported long time ago: viewtopic.php?p=91653#p91653

As a workaround, hide the error by clicking on "Hide", then re-try opening a bookmark (it may take several clicks before it finally opens). After that, all other bookmarks should come up as well.

I will make the devs aware, but not sure there is much they can do about this one since it is DDE related. I will update this thread if anything new comes up.

No it never worked for me, "BMKBUDDY/IgnoreUIPI". As a workaround, hide the error by clicking on "Hide", then re-try opening a bookmark (it may take several clicks before it finally opens). After that, all other bookmarks should come up as well. This did not work either.

I run BB outside of the box, and 5.22 works fine.
What ever changes made to 5.23 broke BB.

Tried 5.24 RC , running BB inside and out side of the box, running inside opens the first page, then get the "SBIE2205 Service not implemented: DDE 000003E6" trying to open a second page.
Running outside of SBIE same thing without the message.

The latest FR version tested is Win 10 x86 17110 . Using Fast Ring versions will most likely cause issues with Sandboxie, as they keep changing things.
I'll upgrade to 17115 and let you know if I can repro.
